If Paradox were evil, they'd design a game where advancing would frequently require you to murder spouses, relatives and children.
Oh. Erm.
If they were evil, they'd make a game which encourages brutal colonization and the wiping out of indigenous nations, while inventing reasons to wage illegal war... hmm...
Ok, if they were really evil they'd design a game where you lead the world's most horrific regimes to victory in the most devastating war of all time. Oh. They did that too? Ah.
Right, got it. If Paradox were truly evil, they'd make a game where success is built on building an economy consisting of slaves, alcohol and tobacco and exporting them round the world. Oh, God damn it!
There's only one conclusion, Paradox is actually a front for the Legions of Satan himself, and the basement of their offices contains a portal to the deepest circles of Hell
